<div><p>Diagnostic commands allow you to monitor the efficiency and performance of your Java application. JDK Mission Control uses a number of different diagnostic tools, including a set of commands that you can run against the application using the <span class="bold">Diagnostic Commands</span> tab.</p>
<p>The <span class="bold">Diagnostic Commands</span> tab is divided into the following sections:</p>
<ul style="list-style-type: disc;"><li><p>The <span class="bold">Operations</span> list on the left contains a list of commands you can execute against the application running on the connected JVM.</p>
</li>
<li><p>The list of command arguments on the right contains the names and values of arguments that you can specify.</p>
</li>
<li><p>The full command with all arguments that will be executed is displayed at the bottom, next to the <span class="bold">Execute</span> button (that runs the command) and the <span class="bold">Help</span> button (that displays the command help).</p>
</li>
<li><p>The result of executing the command or requesting for the command help is displayed in an output panel that expands from the bottom. This panel contains a separate tab for each time you execute a command or request for the command help. In the title of the tab, the date and time of execution is displayed along with the full command.</p>
</li>
</ul>
<p>To run a command, select it in the <span class="bold">Operations</span> list, provide the argument values in the table on the right, and click <span class="bold">Execute</span> at the bottom.</p>
